Description

TECHNICAL FIELD

The invention relates to a doner kebab cutting robot designed in order to automatically cook and cut doner kebab made from red or white meat in minor establishments such as restaurants, hotels in food sector.

PRIOR ART

Presentation of doner kebab with known technique is that the meat is inserted on a skewer and then it is cooked by rotation against the furnace and it is cut by human power by using long doner kebab knife. In this cutting method, the fact that the worker is always subject to high temperature decreases productivity of working. Sweating of the worker due to being exposed to high temperatures prevents that the doner kebab is presented to the customers under required hygienic conditions.

Cooking temperature should be at least 78 degrees in order that bacteria formation is eliminated in doner kebab and it should have a certain fineness and certain width to reach the taste desired. In the known technique, it is not possible to continuously cut the doner kebab reaching to high cooking temperature in the fineness and width desired by using long doner kebab cutting knife by the worker.

Doner kebab is started to be cut by electrically motorized doner kebab cutting knives after classic long doner kebab knives. Yet, achieving a standard fineness and width of doner kebab is impossible due to human factor also in this method. On the other hand, safety precautions taken for the user in terms of electrically motorized doner kebab cutting knives are insufficient.

Invention full automatic doner kebab cutting robots are configured to have internal heat shields and gas control system on the purpose of cooking doner kebab at the temperature desired in a homogenous way and providing energy saving. Cutting may be performed in desired temperature by the usage of heat sensors depending on the preferences of the customers. Knife sharpening may be performed in a safe way by turning on automatic sharpening mode by the help of touch screen.

The invention includes scanner and/or laser (optionally), position sensors (optionally) and control system having software (PLC/PIC), to which information coming from temperature sensors (optionally) is transferred and in this direction, which sends commands that furnace, doner kebab skewer, cutting rod and knife it is connected to are moving synchronously, touch screen, 1 step and 1 servo motor, step and servo motor drivers in full automatic doner kebab cutting robots.

In the known technique, radiant in the furnaces used in doner cutting robots are fired by switches located on the furnace. This action becomes difficult and poses a problem in terms of occupational safety depending on the location of the robot and condition of the place. The automatic controls of radiant and all furnace is provided by using optionally full automatic electric furnace system in some configurations of furnace on the purpose of eliminating this problem.

DESCRIPTION OF THE INVENTION

The purpose of the invention is to minimize manual control of doner kebab cutting on the purpose of making it appropriate for food health, doner kebab cutting standards and safety of the workers with a configuration including scanner and/or laser (optionally), position sensors (optionally) and special production (PLC/PIC) control system with software, to which information coming from temperature sensors (optionally) is transferred and in this direction, which sends commands that furnace, doner kebab skewer, cutting rod and knife it is connected to are moving synchronously. Another purpose of the invention is to provide performing cutting in standards desired with temperature sensors.

Furnace (5) provides the movement of getting closer and away from doner kebab by linear operating ball-bearings and 12 mm diameter shafts. Hence, distance of furnace (5) to doner kebab is adjusted and sensitive cooking is performed. By means of adjusted heat shields (5b) configured on the furnace, equal heat distribution and energy saving are provided. Furnace (5) is designed as a block consisting of three radiant, it has two different types as electric and gaseous (NG-LPG).

Invention full automatic doner kebab robot cutting capacity is max. 25 kg. Doner kebab meat diameter is max. 28 cm and doner kebab meat height is 45 cm. Cutting rod is two types as right and left and cutting diameter may be adjusted to be max. 10 degrees.

Width, length and height measurements of full automatic doner kebab cutting robot are designed in an optimum way by taking in consideration narrow working areas. Weight of robot is kept at minimum by taking into account the carriage and usage easiness. It is kept away from negative impacts such as oil and high temperatures since doner kebab rotation engine (1d) is included in carcass group (1). Working area is increased by means of mentioned design and easiness is provided in terms of cleaning and technical maintenance. Blower manufactured from plastic material durable to high temperature is placed in the connection between cutting rod and carcass and leakage of water and oil into the carcass is prevented and an aesthetic appearance is gained by the robot.
